Hi there.I don´t know if this post goes here.Sorry if it doesn´t.I didn´t know where to put it
I was changing the digitizer on my Desire HD and I realize that that I broke the ribbon on the picture.Can anyone help me about what to do?Thanks in advance.
Sadly been there and done that....Only 1 solution-buy another. This process is next to impossible without lots of experience-parts are very fragile! Your best bet is to buy an entire assembly with the digitizer and lcd already attached. Much much easier, but not easy by any means still. Good luck.

Thanks.I´ll do that.
you can fix that.
google ribbon cable fix and follow the procedure
(can't post direct link)
btw.
this you can't fix because the lines are simply too small
(I'm waiting for new LCD)

Hi again.I change the screen but now the wifi won´t work.I can´t activate the wifi.It says error.It´s like i don´t have a wifi antenna.Any help?
wifi antenna
I think your problem is bigger than an antenna. The antenna is the same one as the gps antenna and is fitted in the panel around the flash leds. If you were to enable the wifi and just could not pick up any access points, then I would say it was your antenna, but if you are receiving an error, it is more likely that either the wifi module is damaged or somehow disconnected.
Do the rest of the radio parts work? i.e. GPS, Cell, bluetooth? Can you tell me exactly what the error is that you are receiving?

The cell,3g and gps are working fine.Bluetooh and wifi aren´t.When I activate the wifi I get an error message(it just shows "error").When I try to activate the bluetooth it just does nothing.
Thank you

You are right.The volume button are not working!I didn´t try them before.What does it have to do with the wifi?I will open it again.

not much, but it is simple test for the flex ribbon.
open the phone and check the flex connection too motherboard
worst possible thing is that you ripped the flex ribbon during removal from middle chassis
2 areas worth checking-the reciever jack at the top of the phone CAN be put on in the wrong direction-red wire should be towards the top of the phone, black towards the bottom. The long, all black wire running by the camera is the bluetooth coaxial cable and maybe not on its connector properly-kind of pops on when right-check both ends. It also could be damaged/pinched running up through the phone. It could also just be a bad component on the upper board and that whole board needs replacing-a pain after what you've done already.
bluetooth/wifi and volume buttons not working
I think yamFZ6 is right. You likely have a cable not fully seated or a damaged cable. Both the Bluetooth and wifi are on the same chip so it makes sense that both of them would fail together, the volume buttons are a separate module, so they are likely all on a single cable that has issues.
One last thing to try before tearing it apart again, do a full wipe and see if it works properly. This is a long shot, but worth checking and can help with troubleshooting if you cannot find any cable issues.
Good luck,
Let us know what you find.

Looks like the black wire (blue tooth coaxial) near the camera is in toward the battery area too far...battery would be pushing in on it every time and could have broken it...admit that's a long shot...but. Starting to feel like a new "upper" circuit board is in order...hope this helps

Do you know where to buy it?
I have seen it for sale somewhere out there but can't find out where that was now. I would look for a "parts" phone on ebay. usually you get more than a fair amount of usable other parts with it. I just did this for that exact issue plus I needed a 'mid frame'. I got just about everything else with it also as the lower, main board was the problem with that particular phone, Got a usable digitizer, lcd, case, extra wires, camera etc etc all for around $60. You also get the added luxury of more practice/expertise with assembly.

Hey people, I was wondering if anyone has had the faulty headphones issue. After a few days, my headphones stopped working properly, there was a lot of static and they need to be pushed and held towards the screen to function again. This is going on with 3 pairs so it's a phone fault.Maybe all the tech savvy experts here can chime in and propose something.
Thanks!
I have the exact same issue since yesterday... I already tried to clean the headphone jack with no effect so far.
I will unscrew the device and have a closer look at the headphone jack when I find time. Probably not today.

Sadly it's not the same problem visi0nary describes on his blog. The Mass contact is fine.
I had the phone open for a few minutes and it seems like all contact wrap thight around the plug. I guess the problem is a broken soldered point at the back of the circuit board.
I had no time to remove the board completly and check the back.
Maybe you can ask your repair shop guy what he did to fix it? Thanks.

Hey shadowseed,
I took it to a couple of guys in downtown Athens and none said they wanna take a look at an Elephone. And these were techie Asian guys lol. Let me know if you find anything via pm or through here. Thanks. I'll keep looking myself otherwise I'll buy bluetooth headphones.
the problem with bluetooth headphones is that Elephone set the Bluetooth A2DP Bitpool to 35 (basically means compressed data = better range and quicker transfer rate ) which results in terrible sound quality over Bluetooth audio.
I'm not an audiophile but I can't listen to music over bluetooth in my car like I used to with my previous device, it sounds horrible.
This is a software issue but it can't be fixed with a root app or something like this, it's set in the bluetooth drivers. There is a setting under "Sounds & Notifications" called "Lossless BT-Mode", but it does nothing... or not enough, I'm not sure. The Bitpool needs to be raised to 52 or higher for "lossless" mp3 playback.
I wouldn't have bought this phone if I had known this...
UPDATE: I fixed it. This soldering point broke. I didn't solder it, I put a piece of cardboard under the circuit board which presses against the shell. I did this yesterday in the afternoon and used it multiple times since then, it seems to work great.
Put some solder on every point now. That fixed the problems for me, looked like there was no solder there.
Same on my phone >.< seems that the headphone jack has been horribly designed/built then!
The design is excellent, but there are multiple points with no solder on top, just glued or something. That can obviously not work in the long term.. The fix is very easy if you have a soldering iron, you don't need precision tools.
Hello
I have the same problem. I've bought it a few days ago (it has not one month).
What can I do? This phone is warranted?
Thanks,
Diego

Could you please give us a detailed tutorial on how to open up the elephone?
I've tried it today (got the same problem) and failed on removing the white case from the fingerprint scanner.
You can see here: KlickKlack
I've tried soldering the points today and the connection seems more stable for now.
No more bzzing in idle when using headphones (Teufel Aureol), but the quality still sounds like some bad compressed mp3.
Pushing the plug (display frontfacing) to the back left seems to fix the problem.
I've tried putting cardboard between the 3.5mm port and the casing of the phone but no luck.
When using in-ears (some cheap philips) there is still a semi-loud bzzing in the backgroud and since the cable goes sideways there is no way of getting a stable connction.
Did I do faulty soldering or might I've broken the port with the soldering iron?

i'm in the business too, since two days, bought a bt dongle, with eragon rom no bad sound issue, but the asycronious in videos of sound and lips movement is bad, so i have to solder...i need an iron, tomorrow i will try, i hope i will fix it. what about warranty??
thanks for the solutions
I don't care much for warranty on a china phone...
I had the problem that the right in ear speaker didn't work but the left one was okay. But after some time even the left got worse and wasn't usable anymore.
Then I opened the Elephone and soldered the parts of the audio jack (like in the picture above).
It improved the audio quality but it still works only for the left speaker. How do I get both working?

A greeting, a good 2016 and thanks to all for their valuable contribution in this forum. Forgive me because I do not speak English. For about a month I bought a Eonon 5165F, specific for BMW.

The problem is that only detects a satellite, both with GPS antenna which is not connected. I measured the voltage on the jack (on the back of the radio) where you screw the GPS antenna, detecting 0 volts. Is there a solution? Thanks in advance and excuse me if I'm wrong section.
I'm not sure I understand your question.
Let me tell you my experience and hope that it answers what your actual question is.
When using navigation software, unless I had a route entered and running, the GPS signal would be lost if I ever exited the navigation program. Unlike when I actually had the program providing me directions; I would still be provided oral directions even if I was on the "radio" screen.
I believe that there is no power to the GPS antenna unless there is a program running that requires it.
First a big thank you for your prompt response. I did not understand the answer, because of google translator. I try to explain better, the problem is that my car radio is only one satellite is with navigation software, both in function gps monitor. This occurs with both GPS antenna connected, both with GPS antenna disconnected. An operator Eonon, with whom they are in contact and which still do not receive information, suggested I check if the voltage on the antenna jack on the GPS was 3.3 volts. So I infer that having measured 0 volts, no current then the antenna does not work and accordingly the car radio is only one satellite.
Google Translate is not helpful. I suggest posting in your own language as well so that someone else might be able to help.
Check the GPS antenna voltage while a navigation program is running.

To be sure you're measuring DC Volt? Eonon is correct you should have around 3,3 volt DC. If not, your HU is probably faulty. If Eonon allows you, open it up and check
if the GPS antenna wire is connected. You can also beep the antenna wire from the socket to the MB connection.
The cable is connected because the first few days the GPS working. I noticed the problem after I plugged a +12 volts from the car battery to avoid losing time and the memories of the radio stations. I did a restore to factory state but the problem remained. I do not know if you can be of help, but after you restore disappeared applying air pin pro. Thank you.

Well, you didn't tell it has been working before you did something. Why don't you load the factory firmware
which might fix your problem. Ask the manufacturer for the correct firmware and instruction how to reload the firmware.
You might also go into recover and clear all various cache, like Dalvik and so on. Ask the manufacturer for information.
I hope that the manufacturer decides to fully answer. Then I will try with different solutions. I will also try to remove the cache with Dalvik, but first, the root. I have the impression that the problem is related to some electronic component burned.

If you only installed software then it's unlikely a hardware problem.

You can check the “ACC” and “B+” wire are correctly connected to your car connectors.
If opposite, exchange the “ACC” and the “B+” wire.

If the GPS function cannot work normally, you can check
1. if the GPS antenna is connected well (check manual)
2. if the GPS antenna is broken (you can try another GPS antenna to test)
3. if there is something wrong in the inside of your head unit (you can ask the seller for help)
4. the GPS software (try another navigation, such as google or waze)
Hope can help you!
Thanks again for all your answers and your advice. I've already checked if the antenna is connected properly. I also tried another GPS antenna. The result does not change. I tried google maps but can not find my position. I do not think they are wrong connections, because the attack is specific to my car. Initially, the GPS worked with these connections. I did not understand what is the thread "B +". I have not updated because Eonon still unresponsive. I wait a few days later I will open the radio and ask you what to check specifically. I thought also to upgrade MCU, what do you think?You could solve? Thanks XDA forum

Don't start to mess around with things that has no connection to the GPS. Have you answered my question concerning when did it fail? I've already explained in this thread what you should do if you open it up. ACC and B+ are the two power connections. B+ is battery power always on/yellow cable . Acc is on when your starter switch/key is Acc position/red cable. No harm done if you switch the two yellow/red. The only thing you lose is radio settings and other memory items as you already experienced.
When did it fail? When you did something mechanical/electronics/software.

Hello I have great news, I solved my problem. Tired of waiting for news from Eonon today I decided to open my car radio. After various voltage measurements have found that the base of the GPS coaxial cable, on the motherboard, there were 3.26 volts (but not on SMA female jack on the back of the car as I had already said in previous posts). Moving the cable was impossible to have tension. After careful consideration of the cable I noticed that she had been made a bad weld on SMA female jack, because the cable was not connected and was only held by shrink tubing. I went to an electronics store and took a piece of coaxial cable with SMA female connector already soldered. I proceeded to solder on the motherboard and everything has fallen into place. I thank all the people who helped me and especially the user halloj. You are strong XDA!
Can you tell me about the fix? I have the same problem on erisin unit for e46, sometimes it works i have signal, sometimes no signal... And it stay with no signal untill the car is off for 2-3 hours, from where shoud i start?

Hi there!
Did you perhaps take a picture of your inside work? can you share it here please?
Thank you!
Be careful when you buy to this manufacturer because I bought more than 4 units and they don't help when 1 unit is defective, only way is to pay shipping back to china when you buy unit from UK warehouse and solution is much easier, send only defective spare part, because I am not willing to pay anything when product is within warranty, and the time I will be without using it.
So they only care about sell, cheap and poor quality devices and later after send few e-mail, they stop answering.
There are other better manufacturers for good car head units so... STAY AWAY FROM THIS BRAND ERISIN!!!!
yeah agree..
worst quality units i have seen so far
what was wrong with your unit?

Erisin are not a manufacturer they are just sellers - they buy from a variety of manufacturers and then sell them on, they know very little about what they sell and are only useful for the occasional firmware release. If you buy from ebay or with Paypal you should be covered though.
To find out who manufacturers your units go to settings/about device, the 3 or 4 letters after "MTCD" will tell you.
The devices have a few bugs but are not poor quality and the bugs can be sorted with help from fellow XDA users.
What problems were you having ? Its very likely that they can easily be sorted.
mate stop telling people what to say it is not polite, specially when you are not 100% sure of what you say
erisin=KLG
they are not sellers, i am 90% sure of that
the units are very low quality. Bluetooth and wifi problems (can't use both at the same time) , and touch screen problems
these are not software bugs that can be sorted. they are hardware
i have had 3 units so i am quite knowledgeable about them, KLG units are just the poorest quality of all

At NO POINT in my previous post did I "tell people what to say". What I did is give advice using my pretty extensive knowledge of these units and their manufacturers
Having dealt directly with several manufacturers of these units, sold some myself, owned around 6 units from different manufacturers and been active in the XDA forums about them for 3 years, I know EXACTLY what I m talking about, I was offering you and @numind help and advice, dont take it if you dont want to, but I know what I m talking about when it comes to these devices as my thanks meter clearly shows.
Its long been established by myself and others on here that Erisin are sellers - I am 200% sure of that, so you are plain wrong when you say that they are not.
You dont have a "KLG" MCU because theres no such thing, what you probably mean is that you have a KGL MCU. If you have a KGL MCU then you have a device made by Shenzhen Kai Ge Le, but Erisin DOES NOT = KGL, Erisin sell units from several different manufacturers, not just KGL and other sellers also sell KGL devices. Indeed I just bought an MTCD unit from Erisin and it has a GS MCU, GS is a different manufacturer - the letters after "MTCD" denote who manufactures your unit, GS are an entirely different company from KGL.
I made no mention of software bugs, I said its highly likely that "any" bugs can be sorted out, both software AND hardware bugs can be sorted using advice on XDA.
If you havent had a unit made by anyone else other than KGL then I m not sure you can say that KGL devices are "the poorest quality of all", but nevertheless I certainly have heard of more problems with KGL devices than others, so I am inclined to agree with that, but the problems can be overcome.
In all my 3 years on the MTC forums I ve not heard about anyone not being able to use wifi and BT at the same time. Have you updated your MCU ? Have you changed anything in factory settings ? If so (I m guessing the answer is yes to both) then you may want to read @marchnz's Cross compatible MCU thread because he has found out that its possible to use other manufactures' MCUs on MTCD devices and this could sort your wifi/BT issues. Also lots of KGL MTCD devices use the Realtec rtl8723bu wifi/BT chip (as do 1000s of other devices the world over from Android head units to computers), it may be something to do with the antennas, KLD MTCD devices also use this chip and people have improved the reception by simply adding longer antenna wires. Maybe KGL have only connected one antenna (the rtl8723bu should have 2) and that is your problem ? In which case it could just be case of soldering on another. Maybe one or both have become detached, I ve heard of the earth lead for the radio tuners on MTCB KGL device becoming detached before. Have you opened the unit ?
I have heard of touchscreen problems before, its often centred around the connector, have you tried re-seating it ? Can you be more specific about your touchscreen "problems" ?
ok i do own 3 other units KLD, KSP and KGL
KGL is the lowest quality and i insist
the unit i have uses the same chip for BT and wifi and this causes interferance. when BT is connected the wifi is useless.. you can search the forum and you will find many posts about that.. my KSP and KLD do not (although they use the same chip for BT) but, i think it is not combined.
I soldered an external antenna but this did not help at all i itried all MCU's but that made no difference..any way it is the implementation of BT and wifi in these units that causes the interference problem on the 2.4Ghz freq. it will not be solved with any software update.
the most serious problem is the touch screen deffect.. the touch screen is a 9 inch, the center part of the touch overlay works ok but 2 cm around the screen the touchscreen has 3 dead zones parallel to the frame so when you draw for example the cursor jumps these dead zones.. any small button that exists on these dead zones is unclickable.
i tried removing the cable change it etc.. and this did not help.

this member has the same problem so it is not a coincidence..
i will probably return the unit and buy something else
i am really not sure who is the manufacturer and who is the seller anymore, and i don't really care.. you might be right i guess and i apologize for that.

OK, we agree about KGL being the poorest of these units then.
It could indeed be down to the mobo and the way KGL designed it, but @marchnz has only recently found out that a lot of MTCD units can actually be made to use other MCU types (unlike MTCB/C units) so it really could be worth you reading his thread as it could help, maybe a KLD MCU for instance, could sort it out ? Its worth trying. And did you have one or two antennas ? You said "I soldered an external antenna" suggesting just one. This could be important as its both a BT and wifi chip.
Does the screen work if you attach a mouse (not that it would help much when driving, although an air mouse might, I guess thats not the point though) ?
I have read of other users buying new screens, have you looked on Aliexpress ?
One of my 9" units has at least a (very annoying) 1 cm gap between the digitiser and the screen, just out of interest does your KGL ?

i might try another MCU i guess as you proposed.. it is the only thing i haven't tried..
by gap you mean a physical gap? void? nothing? ? no my unit does not have that kind of gap.. this is my unit

Almost all px5 units are suffering the bad wifi reception and/or speed.
The closer the wifi source is...the smaller is the issue.
Most of people are using the wifi units by means of wifi tethering from their phones....which is a very close source to the antenna (which is my case)
When arriving home it detects my home's wifi but speed ia very low (when my phone dpes not lack of any speed connected at the same time and from he same place - the car)
So...all we are having similar problems (which can be affected by interference) but specific units are unusable even having the source close to the headunit.
As the software is the same for all px5 units (including the kernel which recently has been updated on the August 3rd ROM published by dasaita) the problem is on the board
We should all open the units and check how our units arw assembled and compare with the ones that are correctly working
The bad quality of soldering on antennas could be the cause of yoir issues...

i have some electronics knowledge.. BT and Wifi both use 2.4ghz so the interfere more or less
this problem occurs in many HTC and Samsung mobile phones also.. and also occurs in most MTCD devices BUT.. the wifi signal is still usable. In my situation playstore fails to even connect, speedtest does not even find a server.. so it is the implemantation.
this device has 2 antennas, one for BT (a cable really) and another for WIFI (another cable).. but it is the chip itself that has the issue.. in my other KSP unit there is interferance and the wifi does slow down but it is not killed like the KGL. I do think the KSP has a separate BT and WIFI chip.. although both state MD725 for the BT in factory settings..
anyway i just tried HA and GS mcu's but the don't help for the touch screen issue.. so it might be a defective digitizer i guess

New motherboard from Dasaita is built by two different chip modules for wifi and bt.
What's is strange is that he new WiFi module is not dual and it seems to be very old

If its only affecting RK3368/PX5 units then its deffo a software problem related to the SoM.

My KLD MTCD unit has holes for a BC6 BT (BT only) module, as used in MTCB/C devices and I have a spare one, I wonder if using that would improve things, leaving the Realtec just to do wifi duties, not sure how youd "tell" the MCU not to use the rtl for BT though.
On MTCB/C units a small heat sink makes the wifi much faster, some people with MTCB/C units also suffer from slow wifi when connected to a router and downloading large files (although I ve not experienced this), but MTCB/C units have separate wifi and BT chips. TBH though all antennas are "cables really" A tiny heat sink is worth trying and costs peanuts. MD725 means its the same rtl wifi/BT chip as KSP/KLDs.
Are all your units MTCD ? Cos if you have an RK3188/PX3 one you could swap the SoM and see if the problem improves/goes away with an RK3188/PX5 SoM, if it does then @ikerg is right and its a SoM/ROM software problem, not hardware, which would probably mean just waiting for updates or hoping a dev on here who knows their stuff can sort it.
Yes I did mean a void, I have two 9" units and one has this void, its weird, just wondered if yours did.
The point is that backlight is dead, only works volume knob led, so I asked to many Erisin contacts if this was a common failure and if they could send to me spare part and I fix it, but they just stop answering.
Also other fail I detected for new PX5 unit is about ignition output filter, there is a sound peak after run the ignition key, and with older PX3 this didnt happen...
Anyway you can't expect too much for these cheap units

How did you pay for it, where did you buy it ?
by paypal I think, via website erisin (dot) com ES6698V
Open a case with PayPal
I think is only possible within 45 first days
Yeah, open a case.

They changed it to 6 months.
Regarding these quality problems from Erisin crap, what would you think could be an option for replace the head unit? maybe Dasaita? some modle in the edge between price and quality, about 400usd...
All people should know about different brands, I would support a kind of satisfaction poll with positive and negative points.

All people should know about different brands, - different manufacturers.
The GS and HA units appear to be the better quality units. For the record, I have a JY and while it isnt bad, there are shorcuts. I have a GS board obtained as a spare part, it was with the GS board I was able to create a Jig to recovery bricked/corrupt PX5 NAND.

Had a problem earlier where the head unit couldn't get a GPS lock. Occasionally I need to close and re-open the satnav application to get a position, however today it just didn't work. After a few resets and it still not working I opened up the GPS Info app and it could see satellites, however it was a bit erratic. I thought it would settle down, however it didn't. I took the video of it but I can't upload it here as video's don't seem to be allowed?
Anyway it just said 'Invalid', the date, time and speed all showed 0 and the number of satellites kept flipping from 1 to 12 with varying levels of signals (23 through 43).
I had to remove the glovebox yesterday as my wife managed to rip out my USB charging socket when trying to connect her phone (AND spilt a can of Pepsi, and she wonders why I don't like her using my car...). The GPS receiver is installed above the glovebox under the dash. Its possible I damaged the cable on re-installing the glovebox but I was pretty careful.
I'll take it apart tomorrow and have a look. Is this likely the cause or could it be something else? It seems odd that it sees a lot of satellites if the GPS receiver is not connected (i.e. cable broken).

Is it an MTCD?

Its a PX5 MTCD (says MTCE with MCU update). Its a GS (Xtrons) unit.
I took the head unit out this morning and tried a spare GSP antenna and it worked straight away.
I then took the glovebox out, removed the original GPS antenna, put the spare in there and re-routed the cable so it hopefully won't get crushed if I remove the glovebox again.
All working now. The GPS cable is quite flimsy. I can see on the original one where it is slightly flattened so it must have been this.
